Common sense...

Nocreativity,

Your post made me chuckle, and wonder a bit whether you were serious or just messing around.  But assuming you are asking a serious question, my main piece of advice for developing more common sense would be:

Learn from your mistakes.

Stop and ask yourself:  Was that a significant mistake that mattered, or am I blowing it out of proportion?

If it mattered... for example, if your action put you or another player in danger of being injured in practice, or if a fielding mistake or running mistake influenced the outcome of an inning or a game... then spend some time thinking about how you can prevent it from happening again, and practice doing it right (either mentally or physically).

Some people may look like they were born with common sense, but more likely they listened to good advice or learned from some not-so-good outcomes of their own mistakes.

The three great essentials to achieve anything worthwhile are, first, hard work; second, stick-to-itiveness; third, common sense.  ― Thomas A. Edison

If you are a kid, you are going to do dumb things.  Coaches expect that.  Every dumb thing you have done has been done before by someone else, probably by multiple people.

I think the big thing is not making the same dumb mistakes over and over again.  I have told my son, don't get on a coaches radar for doing the wrong thing.  Everyone does something boneheaded every once in a while but as long as you are doing the right things the right way (on and off the field quickly, taking practices and warmups seriously, not playing grab tush in the dugout, listening when the coach is talking) then an occasional lapse in judgement will probably be looked at as youthful mistakes.

But if you are getting noticed as a screwup and borderline bonehead then I would work on fixing that fast.  Bad decisions that put players in danger or being known as a guy that doesn't hustle or listen to coaching will get you on a coach's bad side real quick, no matter how talented you are.

Yeah that's true,the mistake you made were not new for the Coach as many of them would have done the same mistake,but most important is that you learn from those mistakes.

when the kid gets clocked in the head he will learn common sense real fast

HAHAHA that's what I was thinking as well.  I learned a lot of lessons this way.  Hopefully this kid figures it out before he gets hurt but it will be a good lesson.
